摘要:
为了解2005—2015年广西西江流域景观格局动态变化,以2005年、2010年和2015年3期遥感影像解译结果为基础,利用景观面积动态度和景观格局指数等方法,借助Arcgis、Fragstats等软件,分析广西西江流域2005—2015年景观格局动态变化特征。结果表明:(1)2005—2015年广西西江流域内景观以林地、耕地景观为主,耕地景观面积呈逐年下降趋势,建设用地景观呈上升趋势;(2)2005—2015年流域内景观呈破碎化发展,景观分散,聚集性减弱,景观的数量、面积、类型呈现多样化,景观结构组成相对复杂,斑块间离散程度或景观破碎程度变高,景观连接性变差。随着经济社会的发展,2005—2015年广西西江流域景观格局动态变化明显。

Abstract:
In order to understand the dynamic changes of landscape pattern in Xijiang River Basin of Guangxi from 2005 to 2015, based on the interpretation results of remote sensing images in 2005, 2010 and 2015, using landscape dynamic degree and landscape index and other methods, with the help of the software such as Arcgis and Fragstats, the dynamic changes of landscape pattern in Xijiang River Basin of Guangxi from 2005 to 2015 were analyzed. The results showed that:(1) From 2005 to 2015, the main landscape of Xijiang River Basin in Guangxi was forest land and cultivated land, the cultivated land landscape area was decreasing year by year, and the construction land landscape was increasing. (2) From 2005 to 2015, the landscape of Xijiang River Basin was fragmentary development, the landscape was scattered. The clustering was weak, the number, area and type of landscape were diversified. The composition of landscape structure was relatively complex, and the degree of dispersion between patches or the degree of landscape fragmentation increased, and the landscape connectivity became worse. With the development of the economy and society, the landscape pattern of Xijiang River Basin in Guangxi changed significantly from 2005 to 2015.
Key words:  landscape pattern  landscape index  dynamic change  Xijiang River Basin  Guangxi
